One term of this invention, illustrated in Figs. 1 to 12, inclusive, isshown embodied in a machine of the type shown in Letters Patent et theUnited States No. 1,556,957, issued to lVilliam H. Robertson, October13, 1925.

The embodiment `illustrated in these tigures comprises the usual amountkeys, means for entering amounts in a totalizer and for printing thesame, and means for printing the total of amounts entered, the printingmeans above -mentioned being simply indicated in this application, asthey are fully shown and described in the above mentioned applications.In addition, mechanism is provided for indicating the total amount. Aflash device, which covers the indication While items are being enteredby the amount keys, is also provided.

Referring especially to Fig. 1, the invention is shown in connectionwith the woll knon'n lever key type ofi machine. The keys 30, arrangedin denominational groups, as shown, are pivoted on a transverse 1od 81carried by the side iframes oit the machine, and at their rear'cnds arenotched to cooperate with a lip on a key coupler 32, for purposes Wellknown in the art. Uprights 33 connectcd to the rear ends of the keys areprovided With notches 34; 'for engaging rods 35 carried by a rockermember 36 supported on a shaft 37. There is a rocker .member for eachdenominational group of keys and each ot the members is operativelyconnected to its registering segment or totalizer actuator SSS. llienotches in the nprights 33 are located to transmit amounts ot movementto the actuators proportionate to the number ot units represented bv thekevs to which said uprights are connected.

The totalizcr actuators are normallv in mesh with Atears 3l) which areoperativelyv connected with the item type wheels (not shown) bj.' a tubeline il() to print the items on an issuing' receipt.

The kcv coupler 1:32, betere referred to` is pivotally mounted in theside trames and rests upon the rear ends ot the ke'vs trom which itreceives its movement. rlie right hand end ot the key coupler carries aroller stl (Fog. lo) which cooperates with a slot in a driving; membercuided on a stud il?) projecting troni the trame ot the machine. Thedriving' member is provided with opposing racks adapted to be throwninto mesh alternatel)- with a gear l5 on a cam shaft ttl to move theshaft in a clockwise direction. rthe engagement ot the racks with thee'car is effected and maintained b v a spring); 4J and a spring-drawnarm 4S and a fiance 49 on the rack and a Vllans'e 50 on the trame,operating in the usual manner.

The anionnts represented b v the keys depressed are entered on atotalizer 56 (Fig. l). which is ot a well known tvpe and will be butbrietlv described.

The totalizer elements comprise pinions 57 rigid with the near wheelsand the other iiecessarnv elements supported on the turn-to- Zero shaft59. The shaft is provided with a groove to cooperate with spring-pressedpawls (not shown) on the totalizer elements to turn the totalizer toZero in the usual manner.

The totaliz/.er is rocked into mesh with the actuators and transfers areetlccted bv mechanism en wcll known in this tvpe ot machine that it willnot be described here.

r[he amount :ucumulated ou the totalicer is asiurtaincd bv a printingand indicating operation. For this purpose. mechanism is provided torsetting' up total tvpe wheels to print the amount on the totalizer andtor lSelecting` indicating elements to displav the the amount.

To accomplish this purpose. the totalizer comprises a plurality otstepped plates GU (Figli rifid with gear wheels til mounted on a rod G;in the totaliz/.er trame and meshing with the gears 58 above mentioned.

The total tvpe wheels (not shown) are located on the rig'rht hand sideot the machine and are connected bv a tube line Gil (Fis. 2) with gears(il in mesh with ment gears (l5 rigidly connected with se; nient .cgears(36 in mesh with segment gears 6T. The segment gears 67 are connected bva tube line d8 (Fig. T) to a plnrahtv ot arms 59. which are adapted tobe moved into engagement with steps on the disks 60 olE the totalizer.rl`he tube line 68 is supported by a rod 70 which actuates the units arm(it) and is supported b v a bracket- Tl carried by the right hand sidetrame and by a bracket 'T2 supported by a cross bar 73 (Fig. l).

The steps on the stepped plates (50 are so located that the type wheelswill be set in accordance with the amount on the totalizer when the arms(59 are moved into contact: therewith. rl`he total indication is alsolected by the stepped plates (S0, as will hereinat'ter be described.

Also integral with the srlgrnnent `gears (S5 are segment gears 8O whichmesh with segment` gear levers 8l provided with portions E52 connectedbv tension springs 83 to a recking member Sil. rthe springs arenormally,Y restrained against moving' the arms 8l. and theretore thetotal tvpe wheels, h); a voke member S5 connected byY a link Sti to saidrocking' member Sil. The member 8l is tiret rocked clockwise and thencounter-clockwise bv cams 8T secured on a driving shaft driven by a gearS9 (Fig. t). rlie fear Slt meshes with a pinion 90 which is integralwith a crank handle 91. Two complete rotations ot the crank handle willrotate gear SS) and shat't S8 one complete revolution. As the rockingmember Si is mored clockwise, the springs 83 are permitted to functionto set up the total type wheels in accordance with the amount on thetotalizer. rEhe tvpc wheels are held in alined position whileirnpressions are being` made hv the usual alinin g pawls 92 en eganinfrnotched plates 93 sccurcd to tvpe wheel gears (El. These pawls aresupported in a Ytrame men'ibcr 9st pivotcd on a rod and act lated b v acam flo on the driving' shatt SS. The 'am .()tl is tast on the drivingshaft titl and receives one counter-clockn rotation on cach totalizingl'operation. One arm T9 ol `trame mene ber f-t extends downw-'ardlv` andcarries a roller QT which cooperates with the peripher v ot cam 9G. Asthis cam rotates. a hiegh spot thereon comes in contact with the roller9T and rocks the 'trame (il and nawls tlf; into diningl position. is theroller 9T the high snot. a nin entre with e hook portion ltl of the armitl-and positivelv moves it to the lel't in Fini. i?. to dist it. thealinino' panls. This movement iff' sisted bv a spring T8 stretchedbetween arm T9 and anv convenient point ot the mecha-V uism.

/iidict/fora.

The indicator tablets ltlO (Fie: lo) are counter-clockwise direction, sothat when the bar 115 is moved toward the left, as above described, theshoulder on the paivl will cooperate with the attened stud 12T andretain the bar in its moved position. The paul 126 has a downwardlyextending portion, on the end of which is mounted a stud 12S. 1t isevident from Fig. 6 that When the arm 1241 is returned in acounter-clockwise direction to its home position, it Will strike thestud 128 and thereby raise the paivl sufficiently for the shoulderthereon to be disengaged from the stud 127. Thereupon. the bar 115 ivillbe returned to its 1 normal position under spring tension. The

thin steel plate 132 for each tablet is cut aivay along its right handedge (Fig. 10) so as not to interfere with its corresponding disk 110.The other plate 130 is not out avvay, hoivever, and extends between itsappropriate disk and the disk just behind it, and thereby prevents anyvmisalinement between the disk and its lever 105.

By referring to Fig. 2, it ivill be apparent that the rocker 8-1 Willhave been rocked into itsl forward moved position, after the cam hasrotated approximatelj7 600. This movement as stated before permitsadjustment of the total type `wheels under control of the totalizer. Thecam 19T ivhich operates the retaining bar 115 for the levers 105 of theindicator tablets, is so formed that the retaining bar vrill not bemoved into its completely ineffective position before the cam 19T hasmoved approximately 90. It is thus clear that the retaining bar 115retains the levers 105 out of engagement ivith the disks 110 as thedisks are being adjusted and for an ample time thereafter to prevent anyinterference of the levers 105 ivith the proper adjustment of the disks110.

The means for moving the selecting disk 110 differentially under thecontrol of the Lotulizer elements will noiv be described. 1t will heremembered that each totalizer element has attached thereto one of thestepped plates o0. These plates are rotated with the totalizer elementsand when a total is to be raken from a totalizer the ting-ers G0 aremoved clockwise (Figs. 1 and 2) until the bent ends thereof come intocontact with Whichever one of the steps has been positioned beneath it.1n this Way each of the lingers 00 moved diilere; n v to an c3;- tenteipial to the complement of the amount upon its` appropriate totaiizerwheel. The selecting lingers G0 are clearly shou'n in Fig, T. The onefarthest to the right, as seen in -.his tigure. cooperates ivith theunits totalizer uheel, and it is therefore necessary that this finger beconnected vrith the selecting disks for the units indicators. Thisfinger is attached to a hub 135, ivhich is fast on the shaft 70. Alsofast on this shaft is negarlo an arm 13G carrying a segment (fear 137(Fig. 1). This segment gear meshes with a pinion 138 loosely mounted ona shaft 139 supported by the machine side frames, and is fast to theside of a spiral pinion 140 (Fig. 7), which in turn meshes with an otherspiral pinion 111 fast on shaft 112 appropriate to the set of disks forthe right hand or front units indicators. It is, therefore, evident thatwhen the units linger 69 is moved. the movement will be transferredthrough the shaft T0. arm 13G, segment 13T, pinion 1238, spiral pinion1&0, and spiral pinion 111 to the shaft 112. Each of the shafts 112carries a pin 1 (Fig. 1) Which projects through a slot 1113 in the hub111. supporting the disks 110. A coil spring 111- surrounds the shaft112 and at its rear end is anchored in a coltar 1&5 fast on said shaft.At its forward end the spring engages vvith an opening in the end of thehub 111 for a purpose later set forth. TVhen the shaft 112 is rotated incounter-clockwise direction, as viewed from the front, the pin 1/12which is in contact vvith the end of the slot 143 Will rotate the collar111 and thereby the disks 110 into a position corresponding to theaniouut on the totalizer Wheel.

The units of cents shaft 112 for the front indicators is driven directlyfrom the units of cents linger, as above described. Faston the shaft 112is a gear 156. Cooperating With this gear is a rack 15T (Fig. S) whichalso meshes ivith a gear 158 fast on the left hand one of the shafts 112Which shaft carries the selecting plates for the units of centsindicator group which indicates toward the rear of the machine. Tt. isessential, of Course, that both the front and back indicatorscorrespondingl to the same denomination be actuated simultaneously tothe saine extent, and this is accomplished by means of the rack justabove described. All of the groups of indicators and selecting platestherefor are duplicates of those for the front indicators. and thereforeno further inentiou need be made thereof.

The second finger from the right, as seen in Fig. T. is connected by ayoke 11T to arm 11S. identical vvith the arm 13G. This arm carries asegment gear 110 which meshes with a pinion 150 fast; to the side of aspiral pinion 151. meshing with another spiral pinion 152, fast on ashaft 151. supported by the indicator frame 102. and by a bracket 155carried by said indicator frame.

fr rack 150 similar to the rack 15T. aliiovc described, cooperates witha gear 160 fast on shaft 151. This rack also eooperates ivith gears 101on the shafts 112 appropriate to the tens of cents indicaror groups forboth front and back indicators. lt is therefore evident that theadjustment of the finger 69 by the tens of cents totalizer Wheel will betransmitted, through the above described mechanism, to the selecting)lates for both the t .iut and back tens oi cents indicators.

The third linger 69 from the right, as in Fig. 7. is for the units ofdollars totali wheel, ano it se up the units ot dollars indicators bothfront and back by similar means to that just described with reterence`to the tens ot cents mechanism. 1t is therefore thought to beunnecessary to further describe this mechanism.

The fourth linger irom the right approto the tens of dollars wheel has ahub .:st thereto, which is connected with a similar hub 16'.y by aclutch connection. Fast to the hub 16-1- is an arm 165 carrying asegment gear The movement imparted to the segment gear 166 by the fingeraprn'oprialo to the tens of dollars totalizer wheel, is transmitted bymechanism similar to that above described, to the tens of dollarsiiidicators both 'trent and rear by means ot a suitable rack, shown inFig. 8.

The lest linger corresponds to the hundreds oit dollars totalizer wheeland is connected by means ci' a yoke member 167 to an arm 168 and asegment gear 169. This segment gear co-operates with a pinion and twospiral pinions identical with those above ,"cribed, and diilerentiallysets the selecting i. s 119 lor the hundreds of dollars indicater group.This group is the center group, as seen in Fig. 7, and it is thereforepossible 'to indicate both toward the front and rear with the sameindicators, and therefore only the one gironi.) is provided.

.fitter all ot the groups ol selecting disks are dillerentiallypositioned, they are alined, and the mechanism t'or accomplishing thisfunction will now be described. Fast to each et the hubs 111 whichsupport the selectseen disks a notched disk 180 (Figs. 1, I andCooperating with these disks are arms 182 which are normally out of x;enmnt with the notched disks 180.

e aliners are mounted on a shaft 181. hey are rocked into engagementwith the is 186 at the same time that the alining` parels 92 areoperated to aline the total type wheels. (lne side olf the frame 911,which supports the parwls 92, has an upwardly eX- tending portion 183(Fig. Q). Fast on the slrtt 181 is a downwardly extending arm 184 l ifilles in theplane ot the arm 183. Then pciwh; 9&5 are rockedcounter-clockwise 2), as above described. the arm 183 will ro wt with anarn. 181 and will thereby roc the shat't 181 clockwise, which will bringthe pointed ends ot the a'lining arms 182 into one. nient with the.notched disks 189 if each n oup ot imlicator selecting disks and will.therefore. aline these disks properly. The :diners 182 remain inengagement fith the notched disks 189 for a short time after the shalt112 lr ve started to rotate roversely to normal positions. This ispermitted by the slot and pin connection` between the shatts 112 andhubs 111 which carry the selecting disks. Vlien the aliner is withdrawn,the spring les will rotate lthe disks until the pin assumes the positionin the end ot the slot 143, as shown in Fig. 1. f

Mechanism provided to lower the indicators which ywere exposed at thelast preceding total printing operation after the disks 110 have beendifferentially positioned, in accordance with the amount standing on thetotalizer, and to raise the selected indicators to an exposed position.This mechanism will now be described.

An indicator litter 185 (Figs. 5 and 6) is provided which extendslaterally across all ot the groups of indicators. t is composed of twoside plates and two end plates. Ektending between the two side plateso1' the litter, adjacent each ot the groups ot indicator tablets7 is ashort, flattened rod 186 which is adapted to cooperate with the shoulder107 or the selected indicator tablet 169 in each group. This mechanismis clearly shown in Fig. 10. The end plates ot the lifter entendupwardly and have studs 187 and 188 which project through slots 189 inthe end plates ot the indicator trame 102 and serve to guide the litterin its vertical movement. Pivoted to the stud 187 at each end of thelifter is a link 190 which, at its lower end, is pivoted to an arm 191tast on the shalt- 123.' Also last on the shalt 123 is a partial gear192, with which a segment gear 193 carried by an arm 19st cooperates.The arm 194 is tast on one end ol a short shaft 195 which is supportedby the right hand side frame oi the machine and which upon its oppositeend carries an arm 196 *igsu 2 and This arm carries a roller whichcooperates with a cani groove in a cani disk 197 tast on a shait 198supported by the machine side Jirames. This shaft and cam 197 are givena complete clockwise rotation upon every totalizing operation by meansot a gear 199 also tast on the shaft 198 which meshes with the gear 89,above mentioned (Fig. fr). Upon the clockwise rotation ot the cam disk197, the arm 196 will be rocked counter-clockwise, which movement willrock the arm 194 and segment 19B counter-clockwise (Fig. and rotate thearm 191 clockwise. This movement, through the link 190, will lower theindicator lifter185 andy will thereby bring the last exposed indicatorsback to their normal lowered positions. As the cam disk 197 continuesits movement. the segment gear 193 will be returned to its normalposition, as shown in Fig. 6, which will raise the indicator litter tothe exposed position. As the lifter is raised, the rod 186 correspondingto each of the groups of indicator tablets will engage with theshoulders 107 oi the levers ot the selected indicator tablets, whichshoulders have been ,positioned in the path ot the rods 186 and willthereby raise the selected indicator tablets to a position in which theymay be seen through glass covered openings in the' trout and back ot thecabinet. The plates 132 ot' each indicator have projections li') whichwill be engaged by the studs 186 on the downward movement ot the litterto positively lower the exposed indicators.

A llash mechanism is provided which will obscure 'the indicators duringitem-entering operations, but which will be released and withdrawn upontotal printing operations. This yflash mechanism consists ol front andback members joined at their ends -to torni a rectangular box Q05 (Fig.The tlash is supported at each end by nprights 20G. lt is `guided in itsvertical movement by the two upwardly extendiiig portions 20T ot theindicator supporting trames 102. Near their lower ends each ot theupright4 U6 is provided with a slot 208 through which project pinsmounted in the side trames. rllhese slots and pins also serve to guidethe flash in its vertical movement. F

nach ot 'the uprights Q06 at its lower end is bent to 4entend through aslot in the side trame and has a forwardly extending portion which restson the lip ot the key coupler 32. lt is evident that upon the lirstitem-entering operation, when one oi' the keys 30 is rocked, the keycoupler will raise the llash to a position 1in which it conceals all oithe in- 'dicators The flash is lmaintained `in this raised position bymeans ot a pawl 210 (Figs. 2 and 3) which is normally vheld in Contactwith the rear edge ot tho `right hand upright 206 by vmeans ot a spring21 TWhen the flash is raised by the key coupler, the pawl `210 will berocked clockwise due to the 'engagement therewith ot' the beveledsurtace'ot a shoulder 212 carried by the upright `Q06. It is evidentthat as soon as the shoulder 212 reaches a position above the pawl 210,the `pawl will'snap in lbeneath the shoulder and 'retain the position.

)When a total is taken and a new indication is set, it is desired tolower the llash, and 'this is done in the following` fmanner. The arm195, previously described, which is rocked first counter-clockwise andthen clockwise 'by the cam 19T, Yhas a. projection '213 in engagementwith a pin 21st carried by the pawl 210 out trom beneath the shoul der212 on the right hand tlash upright, which will permit the lla-sh todrop under the influence ot gravity flash in its raised Embed/mentadapted for use in keg/actuated lyacc/zines.

Having described this invention as applied to a n'iaehine adapted toprint and indicate totals an embodiment thereoit will now be de... ibedwhich shows applicants iiulicators used with a key-operated machine otthe general type shown in You ifein, No. 1,371,653, issued March 15,1921. ln this machine the indicators are used to indicate the itemsentered, instead ot totals.

This machine, like the one betere described, comprises a plurality ot'key levers 3() (Fig. 13) arranged in denominational groups, and allpivoted on the cross rod 31. Pivoted to the rear end ot each key is anupright having a. notch 8l located in accor-dance with the *alue of thekey. These notches engage rods 35 carried by rocker members lo supportedon a shalt 3T. There is a rocker member tor each denoniinational groupof keys and each ot' the members is operatively connected to itsregistering segment or totalizer actuator.

The key coupler is similar to the one previously described, and nofurther description will be given here.

In this embodiment ot' the invention, the

indicator selecting disks are set directly by the totalizer actuatingsegments. In Fig` 13 the units oll cents indicators for indicatingtowards the front ot' the machine are shown. It can be seen that thesegment 38 meshes with a pinion 220 (Fig. 18) tast on a shaft Q21supported by the machine side trames. Also Atast on this shaft is aspiral pinion 14() which meshes with another spiral pinion 1-Ll1 tast ona shaft 112. The remainder ot' the units ot cents indicator selectingmechanism is very similar to that above described, and theretore it isthought to be unnecessary to repeat rthe description here. The samereterence numerals as previously used will be applied wherever possible.The only diller ence between the selecting plates for this embodimentand those previously described is that these are normally in positionl'or the zero indicator to be selected, whereas in the previouslydescribed embodiment the disks ymust be `moved to the zero position toselect the Zero indicator.

Fig. 18 shows a machine having two totalizers. A pinion, like pinion220, is also tast on shaft 221 and is driven thereby to position theunits of cents actuating segment 38 ot the letthand totalizer. The shaft221 also drives spiral gears and selecting mechanism for the units olcents indicator adapted to be seen tromthe rearot the machine.

The tens of cents rocker member (not shown) actuates a segment (Fig.18).

lli

segment 222 meshes with a gear 218 tast to the side oi? a spiral pinion224 secured to shaft 239 which in turn meshes with a spiral pinion 225tast on the shaft 112 appropriate to the iront indicator' selectingplates. This shatt carries tast. thereon a pinion 226 which cooperateswith a laterally movable rack 22S, similar to those above described,which in. turn actuates pinion 227 `tast on the shaft 112 tor the tensof cents rear indicators and thereby sets the selectingr mechanismtherefor.

The units of dollars rocher member drives a. segment 230 which is taston shatt 37. Also tast on this shaiit is a segment 231. The movement otthe segment 231 is transmitted through the usual spiral gearing to ashort shaft 232, which carries al pinion This pinion is connected to a.pinion 2311 for the front indicators and also to a pinion 235 tor therear indicators by a rack 236 (Fig. 19).

The tens of dollars rocker member carries a segment 37 (Fig. 18) whichmeshes with a pinion 238 fast on al shait ^Atlso tast on this shal't isa spiral gear 2410 which meshes with a similar `,gear 2111 tast on ashait 112 for the combination front and back indicator selectingmechanism, which is visible both from iront and back.

1t is evident from the above description that the indicator selectingplates are diti'erentially set by the downward movement ot the keys,which will select the proper .indicator in each group for elevation.

After the selecting disks are positioned they are alined by mechanismidentical with the aiining,` mechanism above described, eX- cept in solar e s its operating means is concerned. The :dining sh: :,:arries a,downwardly extending arni which is fast thereon and which contacts Vwiththe upper end ot a lever 2415 pivoted en a stud 24'? on the right handside frame. The lower end ot this lever carries a roller 248 whichcooperates with a cam 249 iast on the revolution shaft 16. This shaft isgiven a complete counter-cloekwise rotation (Fig.

sie,

ir) on every operation, as above described.y

The cam 21119 will rock lever 216 iirst counttn'-clock\vi,se and thenclockwise, which will in turn. rock arm 2&5 and aliniing, shaft 181iirst clockwise and then counter-clofkwise. This movement will rock thealiners into engagement with their appropriate notched disks, which willaline the selecting plates. The arm 24:5 is held in contact with thelever 246 by a spring 250 stretched between a projection on arm 245 anda pin on the side trame.

The means tor exposing the selected indicators to view will now bedescribed.

An indicator lifter is provided which is identically the same as the onedescribed in connection with the previously described embodiment ei theinvention. It is not isi it)` thought to be necessary, therefore, toagain describe this mechanism here. The operating means for the litteris different, however, and this will now be described.

ilivoted to the. litter on each side o't the machine is a link 190,before described. At their lower ends these links are pivoted to arms251 1o) and 252 (Fig. 15), 'tast on a sha't't carried by the sideiframes.

The arm 2. 2, -which is on the riOht side c'r the machine, has teeth251i integral with its hub, and these teeth mesh with a segment mscrewed to the key coupler Tt c ily he that when the key coupler isrocked clockwise by the depression ot any o? the keys, the serment gearwill rotate the arin 252, shatt 258 and arm 251, which movement willlower the indicator litter. lipon the return movement ot the y couplerVto normal, the parts will be L in the opposite direction, whie will 'lethe lifter and expose the selectto view. ls necessary to providemechanism to l the' he7 coupler to return to its norf The weight oit thecoupler ree ot gravita usually dependdo this, but as the additional load indicator litter is placed on f coupler in this construction, thetoln'ieans are provided for assisting' it. i on a .st-ud 256 13) is anarm powerful spring 258 is wrapped stud 256 and cooperates withfarrn toroel: in a clockwise direction.

rounding Vthe key and bearingagainst a collar on said key and said crossbar.

Then the key Q59 is pushed in it is latched in its inner position. rIheinner end ot the key `-arries a pin 262 cooperating;v with a slottoi-med in the lower end ot an arm i263. which is pivoted on the sidelrame. dit its lower end, this arm has a portion bent at right angles tothe vertical portion thereot. lllien the key ispushed in, the arm oilwill be rocked clockwise (Fig. 15). The bent end thereojt, as it movesin, will strike a spring-pressed pawl 261 which is pivoted on an arm 265secured to the key coupler :53 and will rock said pawl clockwise .unt-ilthe bent portion reaches. a notch cut in said pawl, whereupon the pawlwill rock counterclockwise and the key will be latched in its innerposition.

The member 2Go includes a coucentrically arranged substantiallyvertically extending port-ion which moves behind said bent portion otthe arm 2GB as it is lowered upon raising movement ot the key coupler.'lhe parts n'iaintain this relation until the key coupler reaches itshome position, thus retainin` the key 259 in its inner position during'the operation ot the machine. 'ihe recess in the pawl E261 is positionedso that it will miss the bent portion oit the arm 2G23 as it reaches itshome position. The arm 263 beingl tree ot the members Q65 and Q61-permits the return of the key 259 to its outer position.

Fast on the inner end ot` the key i259 is an upwardly extendingl member266 which has a slot surrounding a pin 26T carried by an arm 26S. Thisarm is clamped to a sleeve Q69, which at its opposite end is connectedto a type wheel. lt is evident that the movement ot' the key will set upthe proper clerks initial on the type wheel.

rl`he member 266 also carries a pin Q79 which projects through a slot inan arm 270, loosely mounted on the shaft 221. Also loosely mounted onthis shatt is a hub 271 (Fig. 18), which at its right hand end has adownwardly erden/ding arm QSO Ytast thereto. This arm carries a pin Q81which projects through an openingv in arm 2T() (Fig. 15) and causes` themovement ot said arm to be `ejiven to the hub. At its lett hand end thehub Q71 carries a spiral pinion 272 meshing` with a spiral pinion 273fast on a shaft 275 similar to shaits 112. Fast on this shaft are twoselecting` plates Q76 (Figs. 16, 1T and 1S). Each ot these selectingIplates has a cut-away portion in its periphery with which a lever 10:3ot one ot the two clerks indicator tablets is adapted to cooperate.

lilith the key in its outer position, as shown in Fig. 15, theselecting,` disk 27S tor clerk fif tor instance, will be in position toreceive the end ot its lever 105 and there bv cause the A indicator tobe raised. Lt

however, the key is pushed in, the pin .269 will rock the arm 270clockwise, which movement will rock the hub 271 and yspiral pinion to alike ente The .movement et this spiral pinion will rotate ythe pinion273, 27.5, and disks 276 so as to position the cutaway portion olf thell disk in position to receive its lever 105.

ylhe ik disk Vwill be positiimed to Lnfevimt movement `ot its lever 105and therefore upon the next operation the il indicator will he raised.Upon the next operation, the Si lindicator will be again raised, unlessvthe clerk airain operates the key lYhile the iorm ot mechanism hereinshown an described is admirably adapted to 'tuliill the objectsprimarily stated, it is to be understood that it is not intended tocontine the invention to the one Vform oi embodiment. herein disclosed,tor it is susceptible ot' en'iboigliinent in various toi-ms all coming`within the scope ot the claims which follow.
